La hundido bojas ĉe la pordo.

La is the Esperanto definite article, meaning the.

It appears twice because it applies separately to hundido and pordo:

• la hundido = the puppy
• la pordo = the door

Esperanto uses la much like English uses the. Unlike English, though, Esperanto has no indefinite article. So:

• hundido = a puppy or just puppy
• la hundido = the puppy

Hundido is made from:

• hund- = dog
• -id- = offspring, young one
• -o = noun ending

So hundido literally means young dog / offspring of a dog, which in natural English is puppy.

This suffix is very useful in Esperanto. For example:

• kato = cat
• katido = kitten

In Esperanto, nouns normally end in -o.

So:

• hundido is a noun
• pordo is a noun

This is one of Esperanto’s regular features: the ending tells you the word class.

Some common endings are:

• -o = noun
• -a = adjective
• -e = adverb
• -i = infinitive verb
• -as = present tense verb

Bojas is the present-tense verb form.

It comes from:

• boj- = bark
• -as = present tense

So bojas means barks or is barking.

A big difference from English is that Esperanto verbs do not change depending on the subject. The same -as form is used for all persons:

• mi bojas = I bark / am barking
• vi bojas = you bark / are barking
• la hundido bojas = the puppy barks / is barking

No. The verb ending -as does not show singular or plural.

Whether the subject is one thing or many things, the present tense is still -as:

• la hundido bojas = the puppy barks
• la hundidoj bojas = the puppies bark

The plural is shown on the noun, not the verb:

• hundido = puppy
• hundidoj = puppies

Ĉe usually means at, by, or near.

So ĉe la pordo means something like:

• at the door
• by the door
• near the door

In this sentence, it tells you the location where the barking is happening.

Because ĉe expresses location, while al usually expresses direction toward something.

• ĉe la pordo = at the door
• al la pordo = to the door

So if the puppy is already there and barking, ĉe is the natural choice.

If the meaning were something like The puppy runs to the door, then al would make more sense:

• La hundido kuras al la pordo.

The -n ending usually marks the direct object.

But in La hundido bojas ĉe la pordo, there is no direct object:

• la hundido is the subject
• bojas is the verb
• ĉe la pordo is a prepositional phrase showing location

Since pordo comes after the preposition ĉe, it normally does not take -n here.

So this sentence is fully correct without any -n.

Yes, to some extent. Esperanto word order is fairly flexible, though subject–verb–other information is the most neutral pattern.

So:

• La hundido bojas ĉe la pordo.

is the most straightforward version.

You might also see:

• Ĉe la pordo bojas la hundido.

That can sound a bit more literary or emphatic, putting focus on ĉe la pordo.

Because Esperanto often marks grammar with endings rather than word order, it allows more flexibility than English.

Ĉ is pronounced like ch in church.

A rough pronunciation guide for the whole sentence is:

la hoon-DEE-doh BOY-ahs cheh la POR-doh

A few helpful pronunciation points:

• hundido: stress on DI → hun-DI-do
• bojas: j sounds like English y, so BOY-as
• ĉe: like cheh
• pordo: stress on POR

In Esperanto, stress normally falls on the second-to-last syllable.

Often yes, but not always perfectly one-to-one.

In this sentence, la works very much like English the:

• la hundido = the puppy
• la pordo = the door

But learners should remember two things:

1. Esperanto has only one article: la
2. Esperanto has no word for a/an

So article usage is simpler overall than in English, even if some details depend on context.

Yes. Esperanto present tense -as can cover both simple present and present progressive, depending on context.

So bojas can mean:

• barks
• is barking

In a sentence like this, English would often naturally translate it as The puppy is barking at the door, but the Esperanto form itself is just the normal present tense.
